“…35 Hong reported a similar, publically available design allowing anyone with access to a 3D printer to build the system. 36 However the distance between the lens and the eye is not fixed and therefore a degree of skill is still required to form the retinal image.…”

Complications of diabetes mellitus, namely diabetic retinopathy and diabetic maculopathy, are the leading cause of blindness in working aged people. Sufferers can avoid blindness if identified early via retinal imaging. Systematic screening of the diabetic population has been shown to greatly reduce the prevalence and incidence of blindness within the population. Many national screening programs have digital fundus photography as their basis. In the past 5 years several techniques and adapters have been developed that allow digital fundus photography to be performed using smartphones. We review recent progress in smartphone-based fundus imaging and discuss its potential for integration into national systematic diabetic retinopathy screening programs. Some systems have produced promising initial results with respect to their agreement with reference standards. However further multisite trialling of such systems' use within implementable screening workflows is required if an evidence base strong enough to affect policy change is to be established. If this were to occur national diabetic retinopathy screening would, for the first time, become possible in low-and middle-income settings where cost and availability of trained eye care personnel are currently key barriers to implementation. As diabetes prevalence and incidence is increasing sharply in these settings, the impact on global blindness could be profound.

“…As recommended through describing experiences of regular use (Schmauss et al, 2015), 3Dp should be reserved for complex cases and clinicians should be responsible for decision making. Eventually, hospitals may begin regularly producing their own equipment for clinical use such as 3Dp surgical retractors (Lee, 2016), ophthalmology tools (Hong, 2015) and even simple intravenous bag hooks (Dawood et al, 2015). The use of high-quality 3Dp models within multidisciplinary team meetings in order to enhance communication may also become established.…”

Recent expansions in the development and availability of three-dimensional printing (3Dp) have led to the uptake of this valuable and effective technology within the modern context of medical education. It is proposed that 3Dp is entirely appropriate for the creation of anatomical models for purposes of teaching and training due to the ability of this technology to produce accurate 3D physical representations based on a processed data set acquired from sources including magnetic resonance imaging (MRI) and computed tomography (CT). When investigating the currently available educational research with respect to 3Dp, it is important that the best evidence supporting the practical and theoretical benefits of this technology in teaching and training can be identified, while any obstacles to the effective implementation of 3Dp can also be determined. Here, literature describing recent primary research with respect to the capability and utility of 3Dp in anatomy and surgery have been explored in a narrative review. The impact on resources of implementing this technology within medical education have also been investigated. In order to emphasise wider applications in medicine, the role of 3Dp in medical practice and research have also been examined. To identify recent literature appropriate for this review published up to March 2017, suitable search terms were determined and applied using PubMed and results were judged against an established checklist. The research identified was then allocated with respect to the agreed topic areas of anatomy education, surgical training, medical usage and medical research. A student partnership approach was utilised for this review and the focus of the work was driven by undergraduate students in collaboration with anatomy and medical educators. Preliminary findings from this narrative review support the implementation of 3Dp in anatomy education and surgical training as a supplement to traditional learning approaches.

“…As described by Hong [6], the adapter was designed with computer aided design (CAD) software ( Figure 1A) and printed with a 3D printer ( Figure 1B). The files of the devices are created in Standard Tessellation Language (STL) format which is compatible with standard Fuse Deposition Modelling (FDM) 3D printers.…”

Purpose: To design and develop a low cost downloadable universal smartphone retinal-imaging system and to illustrate its potential clinical application as a teleophthalmology system. Methods: The system involves a phone adapter and a software. The adapter was designed with a computer aided design software and 3D printed. The soft copy of the 3D model were made available online for download and 3D printing in a different region of the world. The software was a custom-designed multifunction iOS application that serves as a teleophthalmology platform. Retinal images were taken from a patient and compared to that of a standard fundus camera.Results: The system was successfully developed and the retinal image taken were of sufficient quality and comparable to the retinal photograph acquired with a standard fundus camera.Conclusions: Our study confirmed that a low cost universal smartphone adapter could be downloaded and 3D printed instantly for retinal photography. The integration of the custom-designed mobile application made it novel and user-friendly.
